Abstract

The invention discloses a memory anti-theft seal. An opening is formed in the top end of a seal body; a seal cover is arranged at the opening of the seal body; a circuit board is arranged in the seal body; a spring gasket is arranged on the lower surface of the circuit board; a contact A and a contact B are arranged on the upper surface of the circuit board; a bulge is arranged on the lower surface of the seal cover; the bulge is located right above the contact B; a small hole is formed in the seal body; a seal line head is fixedly connected with the contact A; a seal line is composed of a copper wire, an insulating layer and an outer packing layer in turn from inside to outside; a copper wire baring part is arranged at a second end of the seal line; a first elastic sheet is arranged on a wall of the seal body; a second elastic sheet capable of being meshed with the first elastic sheet is arranged at an edge of the lower surface of the seal cover. The memory anti-theft seal provided by the invention has the advantages of capability of effectively confirming damaging time of an ammeter, simple structure, easiness in realization, low cost, simple and quick operation, and the like.

Description

technical field [0001] The invention relates to a memorable anti-theft seal. Background technique [0002] In the process of electricity inspection, it is often found that electricity thieves destroy the seal and modify the meter to steal electricity. After being discovered, he denied the time of stealing electricity in every possible way in an attempt to reduce the punishment. At present, there is no effective means to determine the time of the user stealing electricity. Generally, the electricity consumption information collection system is used to analyze the user's electricity consumption behavior, and then roughly determine the user's electricity theft time. However, this kind of judgment on the user's stealing time through the electricity consumption information collection system is not very accurate, so it is very prone to disputes. Therefore, it is very necessary to arrange a device on the ammeter so that the time of stealing electricity is relatively easy to be ac...
